For two parts, that is, it is located at region A (i.e. non-slotted area corresponding viewing area) on the downside of cut-off rule X-X ' and positioned at cut-off rule X-X '
Upside and positioned at slotted zones C two region D (i.e. the corresponding viewing area in slotted zones).In a related embodiment, it needs in week
Border area be arranged GOA circuits, GOA circuits include multiple GOA units 02, in slotted zones C due to fluting setting, for region D
Single-ended drive is only carried out by GOA unit；And be also required to GOA unit in region a and driven, but with the GOA unit of region D
The difference is that：It is both provided with GOA unit 02 in the peripheral region of the region both sides D, i.e., region A is carried out by GOA unit
Both-end drives.In this way, being had differences for the driving capability of region A and region D for GOA circuits.In addition, due in viewing area

Include the first GOA unit 410 driven to the pixel unit of first area D and the pixel unit of second area A is carried out
Second GOA unit 420 of driving.
Based on above-mentioned, in first area and viewing area that this example embodiment passes through cross-notching area both sides except first area it
Outer second area is driven respectively using the different GOA unit of driving capability, to not increase compensation circuit additionally
In the case of reach driving and load the problem of balancing each other, brightness disproportionation one can be improved and realize display screen
Narrow frame.
Hereinafter, will describe in detail to above-mentioned array substrate in conjunction with Fig. 4 and specific embodiment：
In this exemplary embodiment, array substrate includes being arranged in the pixel circuit of viewing area and setting in peripheral region
GOA circuits, GOA technologies are a kind of gate driving circuit (Gate Driver IC) to be integrated on array (Array) substrate
Technology.Wherein pixel circuit includes multiple pixel units, and each pixel unit includes thin film transistor (TFT), pixel electrode and public affairs
Common electrode is identical equal in traditional technology, and details are not described herein again.Wherein GOA circuits include a plurality of grid line, multiple GOA units with
And various input signals (such as clock signal), one end of grid line connect pixel unit, the other end connects GOA unit, and GOA is mono-
The structure and composition of member is no different with traditional technology, is also repeated no more herein.
It should be noted that GOA unit includes input module, drive module, output module, control module, buffering mould
Block, pull-down module, keeps several modules therein such as module, charging module and discharge module at pull-up module, specifically can basis
Circuit needs change, and no longer illustrate one by one herein.
Drive module therein includes driving transistor, usually selects metal-oxide-semiconductor as driving transistor.GOA unit
Driving capability is related to the size of driving transistor, and the size of driving transistor is bigger, and the driving capability of GOA unit is also bigger,
Specific reason is as follows：Metal-oxide-semiconductor forms conducting channel between source electrode and drain electrode, and the breadth length ratio W/L of the conducting channel of metal-oxide-semiconductor is (i.e.
The ratio of wide W and long L) it is bigger, the source-drain current Ids of metal-oxide-semiconductor is bigger, and formula is as follows：
Ids=1/2* μ * C* (W/L) * (Vgs-Vth)2；
Wherein μ is the carrier mobility of transistor, and C is the unit area gate oxide capacitance of transistor, and W//L is crystalline substance
Body pipe gets at breadth length ratio, Vgs between metal-oxide-semiconductor grid and source electrode between voltage, Vth is cut-in voltage (or the threshold of transistor
Threshold voltage).
Usually under the premise of the length of metal-oxide-semiconductor is certain, the Ids electric currents of driving transistor and the W of raceway groove are proportional,
To known to GOA unit driving capability and driving transistor channel width-over-length ratio proportional (namely with ditch road width
Spend direct proportionality).Increasing the size of driving transistor helps to enhance the fan-out capability of circuit, can be reflected in improvement
It rises along time Trise and failing edge time Tfall, bigger because loading, the delay time on signal wire is bigger, and signal rises
Also longer along time Trise and failing edge time Tfall, i.e. Trise＆Tfall=k*RC, wherein k are coefficient, and RC indicates negative
The size of load.
In this exemplary embodiment, the driving capability of the first GOA unit pixel unit corresponding with first area
Number direct proportionality, that is to say, that certain one-row pixels for first area and for certain one-row pixels of second area,
The number (number for the pixel unit that namely each first GOA unit is driven) of the pixel unit of the slotted zones sides C is few
The number (number for the pixel unit that namely each second GOA unit is driven) of pixel unit on the downside of the C of slotted zones, because
This, with the reduction of number of pixels, is supported on reduction, the driving energy of corresponding GOA unit from second area A to first area D
Power should also reduce, and to reach the balance of driving and load, can improve driving and load the display generated under mismatch case
The problem of brightness disproportionation one.
Circuit according to Fig.4, is improved the circuit in related embodiment, i.e., from by increasing compensation circuit (i.e.
Increase load) so that load and the driving is reached balance, it is changed to the pixel unit number by being driven according to different GOA units
Difference so that load and driving is reached balance to be driven using the GOA unit of different driving ability, without increase
Compensation circuit.
Fig. 5 shows a kind of schematic diagram of the array substrate provided in another example embodiment of the disclosure, as shown in figure 5, with
Shown in Fig. 4 the difference is that：In the both sides of slotted zones C further include transitional region in array substrate 400 shown in fig. 5, that is, exists
Slotted zones both sides are divided into first area D1 and transitional region D2, and wherein transitional region D2 is located at first area D1 and second area A
Between.
Correspondingly, the GOA circuits of the slotted zones both sides C are in addition to including driven to the pixel unit of first area D1
One GOA unit 411 further includes the third GOA unit 412 driven to the pixel unit of transitional region D2, and the 3rd GOA is mono-
The driving capability of member 412 is between the driving capability and the driving capability of the second GOA unit 420 of the first GOA unit 411.
Based on the introduction to array substrate described in Fig. 4 it is found that in third GOA unit 412 driving transistor size
Between the size of driving transistor in the size and the second GOA unit 420 of driving transistor in the first GOA unit 411.
It should be noted that the variation in the attached drawing of the disclosure for pixel unit number in the viewing area of slotted zones both sides
The design of the chamfering in figure in edge of display area is not considered, it is main to consider the feelings because of the pixel unit number variation that fluting is brought
Condition.
Fig. 6 shows a kind of schematic diagram of the array substrate provided in another example embodiment of the disclosure, as shown in fig. 6, Fig. 6
Shown in the both sides of slotted zones C also include transitional region in array substrate 400, but with shown in Fig. 5 the difference is that：Transition
The driving transistor of pixel unit in the D2 of the region not only same size of isomorphism is driven, and can also be that two kinds are arranged two kinds
The driving transistor of dimensions above is driven.For shown in Fig. 6, only show that in transitional region D2 include two kinds of sizes
There are two types of size driving capability GOA units, i.e. GOA unit 412 and GOA unit 413 for driving transistor, i.e. tool.As shown in fig. 6,
GOA unit 412 is close to first area D1, and GOA unit 413 is close to second area A, therefore the driving capability of GOA unit 412 is less than
The driving capability of GOA unit 413.
It should be noted that if transitional region D2 includes three more GOA units of setting, these GOA units
Driving capability can also be to gradually change, i.e. the driving capability of multiple third GOA units of transitional region is arrived along second area A
The direction of first area D1 is gradually reduced.
Fig. 5 and array substrate shown in fig. 6 may be implemented from first area to the secondth area due to the setting of transitional region
The smooth transition of domain display brightness further functions as the effect for ensureing brightness of display screen homogeneity, to transitional region shown in Fig. 5
The GOA unit driving capability that pixel unit is driven is identical, and design is relatively simple；And to the pixel of transitional region shown in Fig. 6
The GOA unit driving capability that unit is driven is also to gradually change, and can further strengthen the homogeneity of brightness of display screen.
It should be noted that the size of the height (line number for the pixel unit that i.e. transitional region includes) of transitional region or
The accounting of the height for saying transitional region and slotted zones height can be modified according to design requirement, for example, transitional region
The accounting of height and slotted zones height can be 1/2,1/3 etc..When slotted zones account for 20 row pixel unit, the pixel of transitional region
The number of unit can be 10 rows.
Fig. 7 shows a kind of schematic diagram of the array substrate provided in another example embodiment of the disclosure, as shown in fig. 7, with
Shown in Fig. 5 and Fig. 6 the difference is that：Transition region is not set in the both sides of slotted zones C in array substrate 400 shown in Fig. 7
Domain, but the driving capability of the first GOA unit 410 entirely driven to the pixel unit in first area is to gradually change
, i.e., it gradually tails off along the number of the pixel unit of the direction first area D far from second area A, the drive of the first GOA unit
Kinetic force is gradually reduced, i.e. the size of driving transistor is gradually reduced.
Though transitional region is not arranged shown in Fig. 7, the driving energy of the corresponding GOA unit in substantially entire first area
